Solvent extraction

Solvent Extraction is a method which requires extracting oil from oil-bearing materials by dealing it with a low boiler diluent as against to extracting the oils by mechanical pressing methods. The solvent extraction system gets better nearly all the oils and leaves beyond only 0.3% to 0.9% remaining oil in the raw product. In the case of mechanical pressing the remaining oil may be somewhere from 4% to 16%. The solvent extraction process can be used sheer to low oil fulfilled raw products. Solvent extraction can also be applied to extract pre-pressed oil acquired from high oil fulfilled products. Since of the high percentage of regaining oil, it has become the most favored process of extraction of oils and fats. Today in big amounts of oil such as peanut, cottonseed, linseed, neem, castor, copra, sunflower, etc. are extracted.
